There is no need to over complicate the issue. Just add a small amount of properly secured weight on multiple test flights and you can tell if the C.G. is going aft by the way it flies. Personally, I'd stop adding weight before it got to "neutral stability". The KR stick forces are so light I'm not sure how you'd measure the difference between flights. I got in a 45 minute flight in the 34 degree winter air yesterday. I held it on the deck on takeoff and got 130 mph in 4000 feet! Cold air was a bit bumpy but visibility was unlimited. Wind right down the runway on landing. Wheels just started rolling on touchdown. I LOVE THE WAY MY KR FLIES !!!!!!!!!!!!!!!!! Larry Flesner
